Abstract—

The electron transport is studied experimentally by measuring pulsed radiation-induced conductivity in polyetheleneterephthalate under bulk irradiation of polymer films by fast electron pulses in a small-signal regime. Numerical simulation is performed using a multiple trapping model with an exponential energy trap distribution. It is shown that, contrary to the reported interpretation of this phenomenon, there is no electron extraction to electrodes under these experimental conditions. In reality, the electron dispersive transport in PET occurs in the presence of the monomolecular capture of electrons by deep traps of biographic origin.

聚对苯二甲酸乙二醇酯中的电子传输

摘要-

通过在小信号状态下通过快速电子脉冲在聚合物膜的整体辐射下测量聚对苯二甲酸乙二酯中的脉冲辐射诱导的电导率，对电子传输进行了实验研究。使用具有指数能量陷阱分布的多重陷阱模型进行数值模拟。结果表明，与报道的对该现象的解释相反，在这些实验条件下没有电子提取到电极上。实际上，PET中的电子分散传输发生在通过传记起源的深陷阱捕获电子的单分子情况下。
